1. Temperature compensating ceramic capacitors boast unique characteristics concerning their capacity-temperature coefficient which is practically unknown in other types of capacitors.
2. In addition, the following advantages are incorporated.
3. Changes in capacitance due to temperature changes are liner and reversible. Moreover, any optional temperature coefficient is obtainable.
4. Compared with conventional types of capacitors, construction of these is much simpler and inductance is negligible, enabling them to function as capacitors up to high-frequencies.
5. Conveniently small-sized.
6. The Q-value is superior from low-to high-frequency ranges.
7. Excellent heat resistance; insulation deterioration due to temperature rise is limited.
8. Capacitors with small capacitance tolerance are easily obtained. No secular change is observed in capacity value.
9. Because of their stout moisture resistance and long-life characteristics, these capacitors can be used permanently under normal conditions.
